We know that building regulations are the minimum standards to which your extension must be built. They govern literally every aspect of construction, exhaustively detailing how things should be. As a homeowner you aren’t expected to know the ins and outs of these, but it is handy to know the main stuff.
The regulations are enumerated over a suite of approved documents, or parts as they are known, with each approved document covering a different aspect of construction. Here is a quick summary of building regulations, at a glance.
Part A, covers structure. Requires structures to be designed and built safely and robustly, so as not to compromise the structural integrity of other buildings or structures.
Part B, covers fire safety. Governs fire risk management, fire prevention and the protection of people and property from fire.
Part C, covers site preparation and damp proofing. Controls adequate site preparation, weather-tightness, below-ground drainage and measures for dealing with land contaminants.
Part D, covers toxic substances. Particularly managing the risks associated with insulation materials.
Part E, covers soundproofing. Sound insulation in buildings and sound transference between buildings and dwellings.

It is useful to have a quick summary of regulations to hand, so when you hear your Architect, Engineer, Building Control Inspector or Builder refer to them, you’ll be able to follow the conversation and speak the lingo.
